config: Add map() interpolation function
* `map(key, value, ...)` - Returns a map consisting of the key/value pairs
  specified as arguments. Every odd argument must be a string key, and every
  even argument must have the same type as the other values specified.
  Duplicate keys are not allowed. Examples:
  * `map("hello", "world")`
  * `map("us-east", list("a", "b", "c"), "us-west", list("b", "c", "d"))`

James Bardin 2bd7cfd5fe Expand list interpolation to lists and maps
Allow lists and maps within the list interpolation function via variable
interpolation. Since this requires setting the variadic type to TypeAny,
we check for non-heterogeneous lists in the callback.

James Nugent 58dd41f3b1 core: Add list() interpolation function
The list() interpolation function provides a way to add support for list
literals (of strings) to HIL without having to invent new syntax for it
and modify the HIL parser.

It presents as a function, thus:

    - list() -> []
    - list("a") -> ["a"]
    - list("a", "b") -> ["a", "b"]

Thanks to @wr0ngway for the idea of this approach, fixes #7460.

Chris Weyl 92e23d2252 add an example of cidrsubnet() being used with ipv6
...as this will hopefully clue people in that this function will indeed
work to manipulate ipv6 networks.

Not that I completely spaced on that for quite some time, or anything
like that.

Nope, not me.  Not at all.

James Nugent b62f6af158 core: Add support for marking outputs as sensitive (#6559)
* core: Add support for marking outputs as sensitive

This commit allows an output to be marked "sensitive", in which case the
value is redacted in the post-refresh and post-apply list of outputs.

For example, the configuration:

```
variable "input" {
    default = "Hello world"
}

output "notsensitive" {
    value = "${var.input}"
}

output "sensitive" {
    sensitive = true
    value = "${var.input}"
}
```

Would result in the output:

```
terraform apply

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

Outputs:

  notsensitive = Hello world
  sensitive    = <sensitive>
```

The `terraform output` command continues to display the value as before.

Limitations: Note that sensitivity is not tracked internally, so if the
output is interpolated in another module into a resource, the value will
be displayed. The value is still present in the state.

Example: `${element(split(",", var.r53_failover_policy), signum(count.index))}`

James Nugent cb6cb8b96a core: Support explicit variable type declaration
This commit adds support for declaring variable types in Terraform
configuration. Historically, the type has been inferred from the default
value, defaulting to string if no default was supplied. This has caused
users to devise workarounds if they wanted to declare a map but provide
values from a .tfvars file (for example).

The new syntax adds the "type" key to variable blocks:

```
variable "i_am_a_string" {
    type = "string"
}

variable "i_am_a_map" {
    type = "map"
}
```

This commit does _not_ extend the type system to include bools, integers
or floats - the only two types available are maps and strings.

Validation is performed if a default value is provided in order to
ensure that the default value type matches the declared type.

In the case that a type is not declared, the old logic is used for
determining the type. This allows backwards compatiblity with previous
Terraform configuration.

Paul Hinze e67fc0fe9b command: Change module-depth default to -1
This means that terraform commands like `plan`, `apply`, `show`, and
`graph` will expand all modules by default.

While modules-as-black-boxes is still very true in the conceptual design
of modules, feedback on this behavior has consistently suggested that
users would prefer to see more verbose output by default.

The `-module-depth` flag and env var are retained to allow output to be
optionally limited / summarized by these commands.

Martin Atkins ef161e1c1b Various interpolation functions for CIDR range manipulation.
These new functions allow Terraform to be used for network address space
planning tasks, and make it easier to produce reusable modules that
contain or depend on network infrastructure.

For example:
- cidrsubnet allows an aws_subnet to derive its
  CIDR prefix from its parent aws_vpc.
- cidrhost allows a fixed IP address for a resource to be assigned within
  an address range defined elsewhere.
- cidrnetmask provides the dotted-decimal form of a prefix length that is
  accepted by some systems such as routing tables and static network
  interface configuration files.

The bulk of the work here is done by an external library I authored called
go-cidr. It is MIT licensed and was implemented primarily for the purpose
of using it within Terraform. It has its own unit tests and so the unit
tests within this change focus on simple success cases and on the correct
handling of the various error cases.

Martin Atkins 0b85d35e87 Rename base64enc/dec to encode/decode.
There isn't any precedent for abbreviating words in the interpolation
function names, and it may not be clear to all users what "enc" and "dec"
are short for, so instead we'll prefer to spell out the whole words for
improved readability.

just simple joining or concatting."

formatlist (combined with join)
makes it easy to satisfy those needs.

Terraform until the flag is removed from the config.

The Terraform configuration syntax defines what arrays are.

The corresponding JSON datatype is called array as well, and
since the Terraform configuration syntax is interoperable with
JSON it makes sense to use the term array to describe them.
